When I wrote this post
on the F-Skewb thread, I started a little bit of research concerning a certain problem I had for some time. I want to share my findings with everybody who might be interested.
Sometimes I like if my pictures melt with the background of my post.
(An idea that I picked up from TomZ some time ago).
So I spend quite often the effort to remove the original, usually white background.
As you are aware, the TP background of posts alternates between white and light grey.
I use Picasa/Google for uploading my pictures. In cases where my post is going to be on TP grey, I make a grey background using Photoshop and picking up the grey background of a TP page.
Here is an example with grey background:
This picture would melt completely with the TP grey as I'm going to show in a second post below.
Problems started when Picasa/Google inroduced an "Auto Enhance" feature roughly a year ago.
After introducing this feature, a white background became light grey and a TP grey became darker grey.
In this picture the background in original
upload photo was flawless white
(I used a different Picasa, non Google+ account to show this effect.)
As you can see the optimization
by Google made the background a very light grey.
Earlier, I did not have this problem. White was white and my grey didn't become darker.
It could be considered a bug, but it is called "auto enhance" as I have read here:https://productforums.google.com/forum/ ... TDYXRTdk6E
I found lengthy discussions on a Google forum where many people were annoyed by this unexpected "Auto Enhance". It seems that you have to switch to Google + (at least temporarily) to get a choice to turn off this function
I turned off optimization in Google + and now the picture background is white:
Originally, I wrote about this problem in the F-Skewb thread and I got a nice PM from Justin (he allowed me to quote him):
Subject: F-Skewb being produced?
Here is a technical question (I do not want to derail the topic, but I can demonstrate the problem here very well):
I use Picasa for uploading my pictures. I made a grey background using Photoshop and picking up the grey background of a TP page.
As you can see above (EDIT3: not any longer, because I corrected it; see comments below), the background is a bit darker than it should be. (I would like the pictures melting with the TP background)
If the image background is made transparent, the colour of the forum tile becomes irrelevant. I use Paint Shop Pro but this should work similarly on other programs:
'Magic wand' the picture, then: File> Export> PNG Optimizer
Select these transparency options:
>OK >Save> Choose location
Example image with transparent background:
Direct link to image if you want to copy it to try on a grey TP background:http://s338.photobucket.com/user/justin ... t.png.html
Btw, I'm using the Chrome browser and assume other browsers can handle transparency alright.
I knew about the transparency feature in .png pictures before, but Picasa creates automatically .jpg files when uploading them.
The nice thing with Justin's proposal is that the transparent background is working on TP white or grey.
Here is the very same image using the identical link
on white TP background:
