If you won't attach an image here so I can check some things out, then email Ronbatman at ron [@] comicspriceguide.com and send him the image and maybe he can tell you if it's the problem, or there's some system glitch.

I got a pic of it off comics.org and submitted it with no problem. what are you naming the file? if you have '1/2' in it, it may not work, as my system warns me that no slashes are allowed in the file name.

comics.org shows 8 covers, CPG has 4, so if you want to go copy the ones CPG doesn't have, and submit them using the missing variants button, have at it. https://www.comics.org/issue/1702584/cover/4/

also, note to admin-- CPG has the title misspelled so I couldn't find it till I searched just Avengelyne. Seraphicide is misspelled as Seraphacide, so the second A is wrong. https://comicspriceguide.com/titles/avengelyne-seraphacide/0.5/plpynx

I see you had this prob last fall, and no one from CPG came along to explain. doing a google search on that phrase gets a ton of answers all above my limited code knowledge. can you attach the image to a post and maybe someone else can add it for you, or maybe see what the problem is? sometimes it's the file name having a weird character or spaces.
