I'm not sure what setting or anything has caused this, but when I resize an image in Image > Image Size, the resized image gets semi-transparent 1px border! There seem no obvious settings to cause something like this.
It does'nt seem to do it 100% of the time, I notice it more when I'm cutting up a design and paste images into new documents. Here I have recreated it with a simple 2-layer image:

Be sure your images is flattened before resizing, the only layer should be the background layer !
If the photo is important, I combine two images: 1, an image downsampled using the bilinear method, and 2 (on top), the same image reduced using bicubic sharper. That gives me a better photo, with only the edge pixels from the lesser reduction method. (First downsample with the bilinear method, copy the result, then go to history and return to the full-sized image, then downsample using bicubic sharper. To finish, paste the copied first image below the second. Then flatten the image or go to File > Save for web.
And yes, sometimes the result is worth the effort.
The best solution I have found for this is to use the old Bilinear sampling method when I need to resize and avoid the 1 pixel semi-transparent border. You can find it under Image > Image Size > Resample: (select Bilinear). It doesn't resample quite as nicely as the Bicubic method, but I find it's good enough and it does solve the problem.
I have had this a few times, just simply add a layer at the back of the document in a single colour like black, or a colour that matches the edges of your work and should be all sorted!
Duplicate the resized layer and merge it down. Repeat. This will remove half-transparent edges of opaque layers. I agree it's a pain in the ass though.
This is an artifact of the resampling method.
If you take a 500px square image of red (no other layers and where the red layer is NOT locked as background layer) reduce it to 100px, the transparency is there when using bicubic resampling, but does not happen when using nearest neighbor.
I tried this with noise-filled layers and it still occurs, but is a lot less noticeable.
