Searched the Joomla forum for 2 hours yesterday and the only solutions I found involved hacking the core code -- not a recommended solution.
These two plugins installed in seconds and SOLVED the problem with very low overhead. Well worth the price of admission.
Best feature is the ability to throttle photo uploads for clue-less clients. Can be set to re-size huge photos client-side prior to site upload. Works fast and saves a huge amount of server storage space.
Did have a problem with front-end photo management but didn't pursue to resolution since the client did not require this feature. Seems to be a jQuery conflict.
Be sure to use the jQuery "no-conflict" syntax when writing your scripts.
Set-up was quick and painless. Demo site does a fine job of previewing the extension before purchase.
I had created several custom registration fields that needed to be included in the reports and the developer customised my instance for a very modest price. Highly recommended for enhanced reports and export beyond vanilla VM Reports.
A few rough bumps to final configuration but most answers can be found in the developer's forum. Not very customizable but highly recommended for simple selling needs when PayPal is your payment solution.
