GPL License - usage of Icons under GPL in own project ?

Hello everybody,

maybe somebody can give me a fast hint, as I am not really willing to study the whole GPL und LGPL stuff..... I found Icons on the net with GPL and LGPL license by filtering "free for commercial use" on different icon search engines.

My software generates slideshows and those icons should be used insede the slideshow. The software will be distributed and the generated slideshow may be redistributed for free...

Can I use those Icons ?
Do I have to include GPL/LGPL Licence text ?
Do I have to state something inside the readme ?

thanx Gero

If they're icons, they would have been done by just 1 person. That person can (usually) assign multiple licenses.

See if you can contact him/her personally.

well I am using a lot of Icons from different persons and groups....
