Are you able to upload one or two here to test?

When you "Choose File" and click on it, does the file name appear next to the "Choose File" box?? and do you get a small pic displayed lower like this?? My file name in the attached is 101(Small).jpg

If you don't get that, then your files are most likely still too large.

Why do the files have to be so small?

I don't know. Beyond my pay grade.
They need to have a built in image resizer like they added to the forums a few years ago.

This is what I get

That is how it should look. Once you hit the Submit, the pic should display like my post and it will show 1 of 10 images allowed.
You can then go back and add more pics and then click the Update at the bottom OR just keep adding the pics down the line like you did with that one so the file name is shown like what you have.

thank you, i will try it
