DLL Deploying problems

[ahmdsd_ostora]

When I deploy my application to another computer where Qt isn't installed, I have these 2 problems:

1- JPG images aren't shown: while bmp images work well.
2- Phonon doesn't work anyway.

I found some articles talking about plugins and I followed them but in vain.

I want to know which DLLs should I deploy and where to put them. any help for these two problems?

Copy the entire plugins Directory which is under your Qt Installation to your Application path.

thanks for your point.

The problem solved but note these two points:
1- I didn't include the entire folder, it's 36 Mega Bytes, just I took "phonon_ds94.dll" and "qjpeg4.dll".
2- If I put the dlls in "plugins" folder in my app folder, it doesn't work. but I removed the plugins folder and put the two sub-folders containing my dlls directly in my app folder.

so the folder structure be:
<app folder>
.exe
imageformats/qjpeg4.dll
phonon_backend/phonon_ds94.dll
