[TYPO3-core] RFC #13461: bugfix: wrong image-path returned in class.t3lib_tceforms.php if TYPO3-source is symlinked (backend-redesign)

[Stephan N Kellermayr]

just a reminder.

i am about to release a new backend-skin-extension...
if anyone is interested in a redesigned backend (26 different 
CSS-packages and two iconsets), then please take a look at this bugfix.

it is not really complex, but the effect is a colorful and handsome 
TYPO3-life.

best regards, Stephan
