@bird_lover, I absolutely agree - there should be a way to set and update the bio image and text on The Artist page directly from the artist’s DPW Gallery website without having to go out of context to the Account Info page. This oversight was not by design, but rather due to the legacy evolution of DPW as I developed it over the years.
No worries - thanks to your observation, I have added an Update Bio Image & Info item to the top of the Admin Tools menu up at the top-left of the DPW Gallery websites. This link opens a window with the exact same form as in the Bio Image & Info tab in the Account Info page.
As for adding images to your bio text, there is currently no way to do that easily in DPW. To be clear, there is no way to upload images to insert into your bio text through DPW. There is a workaround, however, that Carol used, which is to upload the images elsewhere on the web, such as in another website, on Flicker, on Smugmug, on Photobucket, etc., and then insert HTML image tags with the source of the tags pointing appropriately to your uploaded images. This gets tricky, however: to insert HTML image tags in the bio text editor, you have to switch the editor to source mode, which will show you the HTML source for the currently entered bio text. Beware, this approach is not for the technically faint of heart! Also, a warning: the HTML editor which DPW uses for the bio text editor is not very robust. I have seen it do unpredictable, such as changing the HTML set manually in the source view, and even causing the bio text to appear differently on The Artist page than it looks in the editor. Because of this, I strongly recommend copying and pasting, into a text editor, the source HTML from the editor to save for later if the bio text needs to be reverted.
It is on my list to replace the current editor with a much better one that will allow uploading and inserting of images into the bio text. Unfortunately, my list is long!
