FZ1OA Image Uploading Tutorial
Method #1 -
using the "Manage Attachments" feature while creating a new post
When creating a new reply (using the "Post Reply" button while viewing a
thread), click on the "Manage Attachments" button found down in the "Additional
Options", "Attach Files" section.
Doing so will launch a "pop-up dialog box" entitled "Manage Attachments".
Here, you are given 2 options: specify a location on your computer to
upload images from, or specify a location on the internet (URL) to upload images
from.
To upload an image from your computer, you need to know where on your
computer that image file resides (use the "Browse" buttons to browse folders on
your hard drive and locate the images you wish to upload). To upload an
image from an internet location, you need to provide a valid address (URL) for
where that file resides. Additionally, you need to ensure that the image
files meet the "file size" and "image size" (resolution) requirements, which are explained in
a table in the lower portion of the "Manage Attachments" dialog box.
Basically the rules are as follows:
- the max file size for an image you plan to upload is 300kb
- the max image size (resolution) for an image you plan to upload is 800 pixels
wide by 800 pixels high
BOTH of these requirements must be met. If the original images you
plan to upload do NOT meet these requirements, you can use an image editing
program to MAKE them meet those requirements. This is explained in further
detail here
in a tutorial titled "resizing images using IrfanView" (IrfanView is a handy
free image editing program that can be downloaded
here).
ADDITIONAL NOTE: It is possible to have an image file that meets
the 800x800 max image resolution requirement, yet still surpasses the 300kb file size requirement.
In such an instance, it is recommended that you use the JPEG file format, and
adjust the "save quality" to be slightly less (instead of "100% save quality",
change it to "95%" or "90%" save quality)..... this should help you get under
the "300kb" file size requirement (of course, another option would be to further
reduce the actual height and width size of the image).
Once you have specified valid locations for the image files you wish to upload,
click the corresponding "upload" button to upload those images (see example
below).
WARNING:
If you try to upload three images at the same time (images that
are at or near the "max requirements"), it is quite likely you will encounter a
rather "baffling" error (click here for
the error you will see in Internet Explorer,
click here for the error you will see in Firefox) and you will not be able
to upload the images. To resolve this issue, simply upload the images one
image at a time (browse your computer for the 1rst image, then click "upload";
browse for the 2nd image, then click "upload"; browse for the 3rd image, then
click "upload") rather than trying to upload all 3 images at once.
Once you have successfully uploaded your images, you will be presented with the
following screen:
At this point in time, you have successfully uploaded your images. To
complete the process, simply click "Close this Window" in the upper right hand
corner of the "Manage Attachments" dialog box. Assuming you have already
entered an actual "message" in your reply, simply click the "Submit Reply"
button and you're done.
WORD OF CAUTION: Hot-linking to images
that exist on other sites can prove to be a risky endeavor. Some sites
(especially other forums) will redirect your attempts at hotlinking to one of
their images to an image that you probably really don't want to hotlink
to (in some cases, the image they redirect you to can be downright disgusting).
Be careful when hot-linking to images on other sites (online merchants normally
do not care if you hotlink to images on their site).
Method #2 -
using the FZ1OA image uploader
The FZ1OA image uploader can be found
here.
A password is required to utilize this particular site feature. As stated
in the instructions on the image uploader page,
the password may be obtained by
emailing a request
which includes your real name as well as your user name (and please use the
email address you used to register your account here when sending this request).
Main points to keep in mind when using the image uploader:
- the maximum file size for an image is 1,048,576 bytes (or 1MB)
- JPEG images will automatically be resized to a max resolution of 640 wide by 640
high, with an IJG compression quality of 50.
- image filenames are case sensitive
Aside from the highlighted points above, additional instructions on how to use
images uploaded using the image uploader can be found on
image uploader
page.
Additional reference information regarding digital
images
Resolution refers to the number of pixels in an image. Resolution is sometimes
identified by the width and height of the image as well as the total number of
pixels in the image. For example, an image that is 2048 pixels wide and 1536
pixels high (2048X1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels).
In addition to image size, the quality of the image can also be manipulated.
Here we use the word "compression". An uncompressed image is saved in a file
format that doesn't compress the pixels in the image at all. Formats such as BMP
or TIF files do not compress the image. If you want to reduce the "file size"
(number of megabytes required to save the image), you can choose to store your
image as a JPG file and choose the amount of compression you want before saving
the image.
JPG compression analyzes images in blocks of 8X8 pixels in size and selectively
reduces the detail within each block. At higher compression rations, the block
pattern becomes more visible and there may be noticeable loss of detail. The
subject and pattern in the image is also a factor. For example, a picture of the
blue sky can be compressed quite a bit without any noticeable effects but a
picture of a colorful bird would "pixelate" quite quickly.
By using JPG compression, you can keep the physical size of the image the same
and reduce the amount of disk space required to store it but you will be
sacrificing the quality of the image.
In laymen's terms:
- the larger the image resolution (height and width), the larger the file size
(and vice versa); making your images smaller is one way to meet the requirements
set for the image uploading mechanisms
- the more compression used (in jpeg images), the smaller the file size (and
vice versa); an image with a compression of 50 (or "save quality" of 50
using IrfanView) will be much smaller than an image with a compression of 0 (or
"save quality" of 100 using IrfanView)
- most people use monitor resolutions of 800x600 or 1024x768 (some use even
higher resolutions); therefore, if you post an image that is 600x600, it will
take up the entire height of a screen set to 800x600; if you post
an image that is 800x800, it will show as being larger than the height of a
screen set to 1024x768 (and considerably larger than the height of a screen set
to 800x600); in most cases, images of 650 pixels (height or width) or less
