So here is the solution, it works with Simple plus theme 0.3 Version:
1/ Open the album.php file located in your simple plus theme folder
2/in the head section, you should have this line
`<script type="text/javascript" src="<?php echo $_zp_themeroot ?>/js/slimbox.js"></script> `
Comment this line so it desactivates the lightbox effect, and save the changes you made
`<!--<script type="text/javascript" src="<?php echo $_zp_themeroot ?>/js/slimbox.js"></script> -->`
3/Open image.php, and look for ` <div id="image"> ` , you should see this line
` <?php echo getFullImageURL();?>" title="<?php echo getImageTitle();?>"> <?php printDefaultSizedImage(getImageTitle()); ?> `
4/ Comment this line
5/ Add this line in the ` <div id="image"> ` box :
` [img]<?php echo getFullImageURL();?>[/img]"> `
6/ You're done, hope it helps
