Why cannot upload GIF image?

Every time when I tried to upload a GIF, it always says “invalid file”, even for those of small size. Why?

Last I checked, GIF is not a valid file type for upload on this forum. There may be a message or upload dialog that says otherwise, but I’m pretty sure GIFs are not permitted.

I did see someone used GIF here successfully. And, when uploading images, it was listed with other acceptable formats on the popup window. That’s why I was Sooooo confused.

I’m reasonably sure you can use an externally-stored GIF (a la pasteall.org).

Here’s a test:

http://biology.fullerton.edu/hol/im/batfly.gif

Yup. It works. The bbcode looks like the following:


![url/to/image](url/to/image)

Of course, replace “url/to/image” with the actual URL to where ever the image is.

Thank you guys, I know what to do now. :slight_smile:
