Upload Problem

14 May, 2019 19:26
I am experiencing persistent problems uploading a PNG file. I keep getting an error message stating that "no image or an invalid image has been uploaded." I've never experienced this before. The only difference between this file and dozens of others that I have uploaded in the past is that it is larger. Any help would be appreciated

Hi George,
Sorry about the inconvenience.

How large are we talking about?

Thanks for the quick response.

The file is 10.8 MB large, dimensions 1759 X 1282 pixels.

That should not be a problem. Can you email it to me at

Email is on the way. Thanks!

Issue resolved. The problem turned out to be the software I used to convert the file from TIFF to PNG. I had originally used GIMP 2.10.10 for this purpose. Apparently, the latest version of GIMP introduced some new protocol that rendered exported PNG files unreadable by Astrobin. When I used Nebulosity to convert the file, I had no problem uploading it to Astrobin.
