You need to use layers.

The bottom layer will be a white background, with a gradient from back to white added. (Black at the top)

The second layer will be the reflection of the jar (inverted and slightly faded)

The top layer will be the original jar.

1) Find an image of a jam jar (or whatever) and open it in Photoshop. Go to Menu>Image>Image size and make a note of the pixel dimensions.

2) Use the magnetic lasso (or path tool) to select the jam jar from background.

3) Create a new document that has the same pixel dimensions as the original. Make all the pixels white, and then use the gradient tool to make the top of the image black, and fade it down to white at the bottom.

4) COPY the jam jar selection from the old document and paste it onto the new document. This will automatically create the second layer for you in the new document.

5) Lower the transparency of the layer until the jam jar begins to fade.

6) Use the smear tool, with a large brush, 50% strength, to "blur out" the bottom of the jam jar.

7) Inert the layer by going to Edit > Transform > Rotate 180 degrees

8 You should still have the original jam jar on the clipboard. Just paste it into the document again

9) Use the move tool to adjust the positions of the layers, so that the reflection is lined up properly.

Okay, well first thing i did for that graphic was:
1.to copy the image you gave me and put it on a new layer and flip it vertically(upside down)-
2.then i basically painted out the grey on the outside of the canister so that we didn't have a grey background on our floor as well.-i did this paint out anytime i had to copy a chunk of the original image.--it was mainly done so that the originally image retained it's background quality.
3.now obviously with the flipped image it's all screwy because the reflection is wrong-it needs to be as if you are looking up from the bottom of the canister to the top.-so i made an elipse(just with the round selection tool) and put it down towards the bottom of the flipped image(so that the bottom curve of the elipse cut right across the top of the can's relfection(the top being the bottom of the reflection...i know i',m losing you..)--then i inverted the selection and chopped out the rest of the reflection with the backspace key.
i also then took the elipse selection tool, made another one and chopped off the bottom of the reflection next to the cans base to get rid of overlap.-i took the blur tool and blurred the edge just a little to merge it back into the canisters shadow a little.
4.now i had an inverted image of the original with a curved bottom(a jar with no lid or bowed in top)--which is what you want, instead of the curve of the canister going downward now it is curving up because i cut it in.
5.then i wanted to give a little dark hew to the top of the relflection so burned it slightly with the burn tool.  i then copied that layer and used it as an overlay, put the opacity down to hardly anything like 10% and painted out(with the eraser and a soft brush) the top of the reflection, so that the base of the reflection seemed to brighten a little.(trying to simulate radiosity by giving it a little more reflected color.
6.next i decided to dim the opacity of my original reflection so that we could start looking like a reflection, i put it down to around 40%.
7.i then selected the top of the canister with the elipse selection tool, copied that into a new layer and flipped it.--obviously it has the same problems that the can had, so i had to make another elipse and cut out an inverted portion of the can lid. i took the burn tool and darkened the inside edge of my now smiling lid and put it on top of my reflection with the same opacity. i didn't actually have the bottle of course, so i just guessed at what it looked like underneath the lip of the can. it took a little fitting to get it to merge with the can reflection correctly, i think i stretch it a little.
8.then i took all the reflections, collapsed them, copied that put it on a new layer, and undid my collapse. now i had a version of the refleciotn all together but ontop of my layers in photoshop.  i blurred this horizonatlly alot, then made it a screen and put the opacity down to 5%, this gave a little bit of material back into the surface that the reflection way laying on.
8. after this it was merely touch ups, the can to the left has a layered mask on it's reflection that i painted out to seem like there was a lot of light in the room. the middle one has more tooth to the reflection and a slightly hotter color burn in the reflected area, the one to the right is pretty plain jane.

well, i know this explanation will probably not help, sorry about that, it was alot of messing around and painting, even though it only took like 15 minutes, i hadn't exactly drawn a canister before so i was trying anything.--in the future i can do a step by step in photoshop for you on any object. if i'd have saved it i'd do it now...hehe. anyways--the elipse tool and cutting out portions is the only way to go for me on this, it was more photoreal, instead of fully just painting it, and i think it cam across okay.

Hi Todd, Jason,

Both answers are good.  Originally, I had intended to award Todd the extra 500 pts because he too the time to actually photoshop the image i sent him.

Now, thanks to both of you, I'm at a lost to award the points---too bad i can't split it.  Let me know what you suggest me do!

thanks again guys!
