s/.+(\d{3}).jpg/Gyermekolimpia_Ujvidek_$1.jpg/i
>From your requirement: PIC00001.JPG renamed as Gyermekolimpia_Ujvidek_001.jpg
1. the 3 last digits should be extracted: .+(\d{3}).jpg
2. rename everything before the 3 digits to:
'Gyermekolimpia_Ujvidek_':
s/.+(\d{3}).jpg/Gyermekolimpia_Ujvidek_$1.jpg/
3. rename 'jpg' regardless of the combination of capitalization to
simple 'jpg': s/.+(\d{3}).jpg/Gyermekolimpia_Ujvidek_$1.jpg/i
