By the way, i just found out that there is a limit implemented in this forum regarding the maximum size of media, thanks for the useful information Despairo.
In addition to the image file size limit of no more than 2.5 MB, there are several other technical rules when users want to include images in their posts on Bitcointalk, as explained by the admin below:
Image rules are:
- Must be less than 2.5 MB
- The entire transfer must take less than 3 seconds.
- The proxied server must not keep the connection open for "a long time" without transferring data.
In addition to using the GIF format, you can also use the APNG format in animated images, such as the following example:

With the same image, the file size of the APNG format can be smaller than the GIF format.
