im not 100% sure but i think 30 is just the limit of what you can upload at the same time. and then after saving, you can upload 30 more again. i dont think theres a limit to the number of pics in an album, ive seen ones with 20k+
if you're uploading a picture from your gallery, you'll have to add the link manually for each pic. but if you're adding a photo from a manhwa on mgg it automatically inserts the link (lmk if youre unsure how to do this ^^)
(only if you're using your phone)
open up any random chapter > click the three lines on the top > desktop version (i also click "show gap" when it's a manhwa so it's easier to see how the pages are cut up).
once you enter desktop ver, you can just click whatever page you wanna save and you'll be given the option to select the album then submit.
if you wanna go back to the normal ver, just click "new version" at the very top.

I got few doubts and searched abit on it but those didn't help................can anybody tell me how photos over 30 can be saved in an album( since limit is 30 but there are accounts with hundreds of them in single one) and how link is below
The only basic method I know is downloading each photo and reuploading them in album and deleting them in gallery.......its a bit hectic to again go to recycle bin to delete it.......and so this process again fails to chapter the link presentation..........any advice guys?
