In our earlier article we have demonstrated how we can fetch images attached to notes. Working on the same requirement we have enhanced our examples to develop an image gallery utility to see all the images attached to notes. Here is the complete code for this utility:

<!--This is a Image Gallery utility, which can be used with any entity which have
relationship with Notes, this web resource will show all the images attached to notes -->< html >< head >< style type = "text/css" >
.left - div {
display: inline - block;
cursor: pointer;
}
.right - div {
cursor: pointer;
display: inline - block;
} < /style>< meta charset = "utf-8" >< /head>
<body style="-ms-zoom: 1;">< script src = "../../ClientGlobalContext.js.aspx" >< /script>< script src = "../Script/SDK.REST.js" type = "text/javascript" >< /script>< script type = "text/javascript" >
//variables
var currentImage = 0;
var img = document.createElement("IMG");
var images = new Array;
var TotalImages = 0;
var SectionName;
var TabName;
document.onreadystatechange = function() {
if (document.readyState == "complete") {
//get query parameters
var queryParam = GetGlobalContext().getQueryStringParameters().data;
var fields = queryParam.split(",");
TabName = fields[0];
SectionName = fields[1];
//hide control in case form create
if (isformtypeCreate())
showImageGalery(TabName, SectionName, false)
else {
showImageGalery(TabName, SectionName, true)
getnotesImages();
}
}
}
//check for form create mode
function isformtypeCreate() {
if (window.parent.Xrm.Page.ui.getFormType() == 1) //create mode
return true;
else
return false;
}
//hide/show image gallery
function showImageGalery(tabname, sectionname, flag) {
window.parent.Xrm.Page.ui.tabs.get(tabname).sections.get(sectionname).setVisible(flag);
}
//get images from notes
function getnotesImages() {
var regardingObjectId = window.parent.Xrm.Page.data.entity.getId();
var entitySchemaName = "Annotation";
var odataQuery = "?$select=AnnotationId,DocumentBody,MimeType&" +
"$filter=ObjectId/Id eq guid'" + regardingObjectId +
"' and IsDocument eq true and startswith(MimeType,'image/') ";
if (typeof(SDK) != "undefined") {
SDK.REST.retrieveMultipleRecords(entitySchemaName, odataQuery, getnotesImagesCallback,
function(error) {
alert(error.message);
}, function() {});
} else {
alert("REST.SDK library not available");
}
}
//callback method
function getnotesImagesCallback(resultSet) {
if (resultSet.length > 0) {
TotalImages = resultSet.length;
for (i = 0; i < resultSet.length; i++) {
var mimeType = resultSet[i].MimeType;
var body = resultSet[i].DocumentBody;
images[i] = "data:" + mimeType + ";base64," + body;
}
changeImage(0);
} else
showImageGalery(TabName, SectionName, false);
}
//change image
function changeImage(counter) {
currentImage += counter;
if (currentImage != TotalImages) {
if (currentImage < 0)
currentImage = 0;
} else {
currentImage = 0;
}
img.src = images[currentImage];
document.getElementById('imageGallery').appendChild(img);
}
< /script>< div >< input onclick = "getnotesImages()"
alt = "Reload"
type = "image"
src = "../Image/Refresh.png" >< input class = "left-div"
alt = "Go Next"
onclick = "changeImage(-1);"
type = "image"
src = "../Image/Back.png" >< input class = "right-div"
alt = "Go Back"
onclick = "changeImage(1);"
type = "image"
src = "../Image/Next.png" >< /div>< div id = "imageGallery"
style = "width: 100%; overflow: hidden;" >< /div>
</body >< /html>
