[TYPO3-content-rendering] Transparent Image rendering problems

[goran v]

Hi everybody,

I am trying to embedd a few transparent png-24 icons to a website i'm working at. ALL of these icons are white/greyish and shall be displayed over a darker and colored background - and all of them belong to a tt_news entry.
There are a few problems i'm struggling to solve:

typo3
- renders the images with a white border
- somehow scales them down - although i haven't instructed it to do so

I've read somewhere that for transparent images i should use an additional mask-image-file with the same size as the icon but this would result in additional work in the future, since a high number of additional icons will be added eventually by my client after project completion.
So i'd prefer a solution where i dont have to use 2 icons per icon. 


The project is running on TYPO3 4.5.20.
Maybe there's a mistake in the code - or somebody of you has another idea?


I'd love to hear some advice, so thanks in advance!
