squeeky clutch??

im new to this auto forum and i have recived alot of help, which is greatly appreciated but today i noticed yet again another strange noise lol. whnever i engage the clutch it makes a squeeking noise, the sound is gone while im drving, and it is the loudest when getting into 1st gear. any clue as to why its doing this?

i went out this morning to check that sound, and i noticed while im driving it sounds like its coming from the front...near the tranny, but when im out of the car listening it sounds like its coming from the rear, maybe my differential needs lubrication or i have a bad wheel bearing? oddly tho it only happens when i let off the clutch and its most noticeable when getting into 1st gear from a complete stop. i have no clue as to whats wrong so if i could get some help asap that would be great, i nvr like driving with problems im unaware of lol
