Not only me, my other blogger template designers are also struggling to find a reliable, free image host with unmetered bandwidth.
I tried to upload the images to blogger and copy the image url from the status bar and use it in templates.. but it didn't worked. But, recently I came to know that we can actually host the images( large) in blogger and hotlink,use them in templates, forums,etc.
Here is the trick..
As usual, create a new post in blogger and upload your template images to that post... but don't publish it... keep it as a draft.
Once you completed uploading all the images, Open each image in a new window.
Once, the image is loaded in the new window, what I previously did was to copy the image location from the status bar and paste/hotlink it in templates. But, it didn't worked!
Now, the trick is, many people don't know that the url which we copy from the status bar is not exactly the direct link to that image file... that's why we can't hotlink to that image.
So, what we have to do to hotlink to that image is Right Click on the image and ' Copy Image location'. (for firefox users). For Internet explorer users, Right click on the image and go to Properties and then copy the image url from there.
For the above picture, status bar shows...
which don't work.
And the Real image url we get after right clicking and copying image location is..
Which works and we can do whatever we want.. with unlimited bandwidth :D
Hope this trick will be useful to many people who are searching for unlimited bandwidth image hosts.
