never had a problem

take a steam screenshot copy it
get free program paint . net
open it in that
change the image size to
1920 x 1080
save as jpg file

replace old image and rename it to anything like
jhfjhfhjf.jpg

select ya map in rustugc.exe list
select the new image with rustugc.exe image to upload browse for it choose it
hit the update button

and before ya update it get rid of this crap forever in steam global settings=STEAM CLOUD
Next time ya start the game turn this off forever=AUTOSAVE set it to 0
disable autosave in the editor too=bottom right corner
go in the game install and find the autosaves folder and delete all the autosaves
there is a backups folder in that folder delete all the backup autosaves

steam cloud error=autosaves cause it lose both the cloud and the autosaves=fixed
now the cloud wont screw it up every time ya play test it in the game and it fixes file upload failed errors too and stops steam syncing forever=hooray no more steam client crashes and no more game crashes either=stupid cloud screws everything in ya library up

it also fixes the office crash at punchout bug

update map

no cloud= no bull

Any luck

that should work

yes, i have tried this on numerous occasions, it does not work. Error 25 does not seem to be related to the size or ratio of the image.

I turned off cloud for viscera a while ago, all of the bugs which i have been told that it causes have persisted, such as the settings resetting.

It should be noted that when this error is called, it says that it "successfully updated the item" even though it stops ON THE SPOT when it errors like this, meaning everything before it goes through, but nothing after. Basically the only thing is the data inside the workshop, nothing cosmetic about the page. Not even an update log.

found my issue.

I've been cursed. like, actually cursed. This is a problem that has been on steam for 14 ♥♥♥♥♥♥♥ YEARS and nobody who has it has been able to get it fixed. Not even steam support helps.

have ya tried steam beta use that i do n its way better for the workshop
go in steam settings opt into steam beta it will force steam to update and hopefully fix that problem
praying for ya

i very busy testing 3 unreleased ue5 games currently testing a ue5.5 game my friend made we both came up with an idea n he made it while i got to give awesome new game its name
wont say what it is until it gets a steam page=working on it wont be too long

also try setting compatability mode on rustugc.exe to win 7 n run as admin

also if it wont update the picture go in the level editor load ya map n copy a body part n paste it save map exit editor n copy paste new updated udk file to upload folder rename the .jpg that is 1920 x 1080 size then try updating the map=maybe it will update the pic then

steam screenshot work just make sure set game res to 1920 x 1080 when ya press f12
then use the screenshot as the image
