I have an object that I zoomed in very close and cut out trying to elliminate the background. Is there an easier way to use some type of cropping to simply outline the object so I can paste into a transparent background?

If someone does know how to do this or that I can send the four objects to to perform this I would be greatly appreciated.

here's how you'd do it in photoshop - I dont know GIMP so i cant tell you what these commands equate to but I'd be surprised if it doesn't have them

paste your item as a layer onto a transparent background

magic wand tool the color you're trying to make transparent

you may have to get the marquee tool and shift-select or alt-select to get every pixel of the color you're trying to make opaque

ctrl-x to cut the whole selection once you're happy with it

create a NEW layer

paste the selection into the new layer

adjust opacity as needed

ctrl-alt-shift-s

profit

I can do it in photoshop now that i downloaded that. The problem is when i bring the image into my website it still has a box around it and the transparency isn't there.


All I want is the image to be able to be brought into my website and just that the image and nothing around it.

I have the image trimmed how I would like with the checkered transparent background everywhere else but when i insert it the image still has the dimensions of the box if that makes any sense.

pretty sure the picture has to have "square" dimensions.. the transparency layer is working fine. i pulled it into dreamweaver just messing around and the transparency is fine.

so, to me it sounds like the problem is more in the layout you're trying to create. i don't know enough about website formatting to answer much more..but you've done the background layer transparency thing correctly so that isn't the problem.

nah, the image being square shouldnt have anything to do with it, unless it isn't square and he's setting the width and height

if you see the front page here both the images have boxes around them and are not transparent even though they are on photoshop

maybe i am not doing something correctly when inserting them etc. if anyone can look at the code and see that would be awesome.

is there a 'Preserve Transparency' checkbox or a 'Save for Web' button or a combination of the two somewhere?

Here's your problem, your CSS is jacked and you are trying to use a JPG instead of a PNG or GIF:

background: url(http://www.intheholestoppers.com/images/footer.jpg) no-repeat rgb(202, 206, 209);
background-image: url(http://www.intheholestoppers.com/images/footer.jpg);
background-repeat: no-repeat;
background-attachment: initial;
background-position-x: 50%;
background-position-y: 0%;
-webkit-background-clip: initial;
-webkit-background-origin: initial;
background-color: rgb(202, 206, 209);


the image for your divs that you've set as a background is a JPG

furthermore, if you want that div to be transparent, you should use:

background: transparent url(images/footer.jpg) no-repeat;


that rgb part in there is setting a color for you, and JPGs don't have transparency

^the css was from a template. The header and footer in dark blue are fine where they are. The problem I would like to fix is the light blue coolwater.css background going from the header all the way to the footer and just have my images on top of that.

I have both of those as png files already.

in your css then:

#wrap {
width: 790px;
background: #CCC url(content.jpg) repeat-y center top;
margin: 0 auto;
text-align: left;
}


becomes

#wrap {
width: 790px;
background: #fff;
margin: 0 auto;
text-align: left;
}

Not sure what I did but deleted some things in the css file that were not needed and seemed to have gotten what I was looking for.

Thanks Kiljadn
