I'm having a really big problem with space online. I've exported one flash containing 53 panoramas and the output was around 600 Mb. I have to say, my panoramas are 30 mb, 8888x4444 px. I've tested several image sizes, but I was wondering if anyone of you knows the smallest best image size for still having a quality export.
An average panorama in my eyes needs to have at least 15000px width for the equirectangular image. The more the better - screens are big and provide high resolution theses days . . .
53 panoramas in a tour i mean is counter-productive: people most unlikely will look to all of them . . and leave the site before having looked on what you want them to see the most!
Better split it into different themes - a good structured tour of max. 10 panos per theme . . .
Avoid to tire out visitors by showing too much in one piece . . .
Regarding your question: for such a small size it´s much too much data. Which JPG-compression did you use? Don´t use more than 7.
