Small bug: CurrentItem is shown as readable/writable in the IDE interface help. However, when reading the currentItem, I get:
B4X:
Error description: Property: CurrentItem is writeonly.

More bugs.

1. When the file cannot be found, the image set in SetImageOnFail is shown. However, this image is zoomable, which does not seem normal to me as it's function is to simply indicate an error.

2. The image set by SetImageForEmptyUri is not shown when ProgressBarVisible=True. This might be the correct behavior, however, this is missing in the docs.

3. When I do this:
B4X:
vp.AddImage(vp.File.FromAssets,"play.png")
, the image in SetImageForEmptyUri is shown, and not the play.png from my Files directory.

Amazing, thank you very much works perfect.
Can you please upload the working demo project here so that I can also download to test.

I tested the old demo with latest version of this lib, but always got forced close error as below:

B4X:
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (main) Create, isFirst = true **
