I have been having some problems viewing downloaded pictures from opera mini on my  for a while now. It shows downloading complete but I can't locate the pictures anywhere on my phone. Anyone with a solution please?

I use Opera mini 6.1 and it gives you the option to select your download location. If it is what you are using initiate a download and look at the folder it first suggests its most likely where your pictures have been going.

Note that pictures not put in the default pictures folder of Blackberry will not show in the media/pictures link.

I use opera mini 6.0 and av actually been downloading pictures to my default image viewer, I noticed I couldn't seee the downloaded pix again after I downloaded screen muncher, don't know if that's W̶̲̥̅̊hα̅‎​t̶̲̥̅̊ is affecting my pictures

Use the Files app to navigate to where you normally store pictures. Also check all the other folders one after the other.

Another possibility is that the images did not download completely, in that case you will see a file but no image.
