The TM Image Library tm-img.com is not part of the Talk Morgan forum but was set up by members for the use of Talk Morgan forum members following a debacle with a then popular image hosting site.
tm-img.com uses the Chevereto image hosting software. Some months ago the developer decided that all images with the .JPG extension should be converted to the .JPEG extension. The two types are identical and it is only the naming convention for the extension that differs.
This caused problems for some sites, including those running on UBB.threads as used by Talk Morgan. It did not cause a problem with embedded images but did cause a problem for images used for an avatar on UBB.threads (Talk Morgan) which must be must be .JPG, .PNG, or .GIF
Following my request the developer has now modified the software so that .JPG files uploaded to tm-img.com now retain the original extension.
If you have a file that uses the .JPEG extension (some cameras and Apple), and you want to use it as an avatar, simply change the extension to .JPG before uploading it.
This is not necessary if the image is the be embedded in a post.
If you use an image stored on any image hosting service
as an avatar on Talk Morgan you must use a direct URLfor the image, not embed codes.
For example:
https://www.tm-img.com/images/2019/08/18/000000000000072880_E1.th.jpg
