look into the style.css of your theme;
search for everything where it says ‘border’ within any formatting to do with ‘img’.
for instance:
img
{ float: left;
padding:4px 10px 10px 4px;
border:0;
border:#CCC 1px solid;
}
img.right {
float: right;
margin:10px 0 0 10px;
}
img.left {
float: left;
margin:0 10px 10px 0;
}
a:link img,
a:visited img,
a:hover img,
a:active img {
border:none;
background:none;
padding:none;
padding:4px 10px 10px 4px;
border-top:#000 1px solid;
border-left:#000 1px solid;
}
a:link img, a:visited img
{
border-bottom:1px dotted;
}
a:hover img, a:active img
{
border-bottom:1px solid;
}
take the lines out with ‘border’, apart from those with ‘border:none’.
and maybe adapt the numbers for ‘padding’.
some of the pictures are obviously too wide to fit side-by-side.
otherwise you can tick ‘alignleft’ when you insert them in the editor while wrtiting the blogs. or edit it.
