I submitted a deviation or scrap and deviantART did not keep my images original dimensions. Why is this?
When submitting very large dimensioned images to deviantART we will automatically resize it for you. This is done to not only speed up load times for your viewers but to make viewing more pleasant.
If you would not like this done for you, you can disable this option after submitting your file to your file deck, by selecting to keep the original size from the drop down menu, located below your file deck.
