Show Blogger Image only in Homepage and Hide it in Post Page

To hide images/pictures from blogger posts and make them appear only in homepage, we will add just a small piece of CSS code in our template and then use the class "hidepic" each time we want to hide an image.

Just follow the next steps:

Step 1. Go to Dashboard - Template - Edit HTML

 Step 2. Click anywhere inside the code area and press the CTRL + F keys to open the search box:

 Step 3. Type or paste this code inside the search box then hit Enter to find it:

     }]]></b:skin>

Step 4. Paste the following code just below it

 <b:if cond='data:blog.pageType != &quot;index&quot;'>
<style>
.hidepic{
display: none;
}
</style>
</b:if>

Step 5. Save the Template.

Now, each time you create a post, first add the picture that you want to hide and then switch to the HTMLtab where you'll see the HTML code of the image that you added - it will look something like this:

 <div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEheQfIz26roGAMfSK5FbzqNz1mcl_vvNIW3sSOfUamf-ZltEq3p2M9muLoqQvE4RvYWryBKvNR9to1u45jC2izOaIhqBSE21ZNB3qr8UDPpOrYggokGDN4LWlfbuhMGtqqowp-2Gfa5ip0/s1600/fire_bird_by_fhrankee-d32af8v.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEheQfIz26roGAMfSK5FbzqNz1mcl_vvNIW3sSOfUamf-ZltEq3p2M9muLoqQvE4RvYWryBKvNR9to1u45jC2izOaIhqBSE21ZNB3qr8UDPpOrYggokGDN4LWlfbuhMGtqqowp-2Gfa5ip0/s320/fire_bird_by_fhrankee-d32af8v.png" width="320" /></a></div>

Note: it should be at the exact location where your image has been added 
(if the image is at the middle of the text, then the code should be found at the middle)

Step 6. Replace "separator" with "hidepic" - see the screenshot below:
