How many files are you downloading? A simple solution will be to show one progress bar that tracks the progress of the downloaded files (10 files out of 20 files).
Plan to have files number up to 16-32 ( pictures only )
Idea to have a sort of individual animated "progress" for each picture in gallery, so i need to be able to get downloaded size/file size for each pic
dim H( FilesNumber ) as HttpJob
for c = 0 to FilesNumber - 1
H( c ).Initialize( "", Me )
H( c ).JobName = c
H( c ).Download( FilesUrls( c ) )
Next
'.......
' and somewhere in Timer sub
JobSize = H( c ).Size
JobDownloaded = H( c ).Downloaded
